CRIMPING MEANS FOR PRESSURE CONNECTING AN .AT LEAST PARTIALLY WIRESHAPED PART AND A TERMINAL PART BACKGROUND OF THE INVENTION The presentinvention relates to a press or crimping 1 the disadvantage that thecams in the operating portion of the press are provided with relativelylarge flywheels to avoid the requirement for excessively powerful drivemeans. This produces crimping presses that are large, heavy and veryexpensive. In these traditional crimping presses, only the ram movesrelative to the inserted cable. As a result, the ram moves over arelatively large path, which means greater acceleration with a largenumber of strokes. Accordingly, such crimping presses are also rathernoisy in operation. The large size of the crimping presses is caused bythe large eccentric wheels. This makes it impossible for one operator tosimultaneously attend to several machines. Furthermore,

the replacement of the crimping tool is usually time consuming. It mustfrequently be effected by personnel skilled in adjusting the course ofmovement of the tool and the position of the tool itself. Anotherdisadvantage of these crimping presses is that the cable pieces must beboth introduced by hand and thereafter removed by hand after thecrimping, which also makes it impossible for the same operator tosimultaneously attend to other machines.

It is generally not worthwhile to set up or convert such machinesforsmall production runs.

SUMMARY OF THE INVENTION It is the object of the invention to eliminatethe above deficiencies.

In the crimping means of the invention, ejection means are provided forthe crimped connection. This substantially simplifies operation.Operating personnel are relieved of some work and can attend to severalmachines.

In accordance with a further development of the invention, the crimpingmeans comprise at least one pair of tools, which are moved in oppositedirections. By the simultaneous movement of the operating rams of bothtools, with each ram moving over only half the total tool path, theacceleration forces acting on the machine parts and the noise producedare substantially less than in known machines.

The infeed area for the wire to be crimped may be defined as a laterallyopen slot into the edge of a support. The crimping plane of the wirelies in the plane of feed of the wire. The cable terminal part is raisedinto this plane for the crimping, so that no kinking of the cable or ofthe terminal part occurs.

By further developments of the invention, the crimping means can havevery small dimensions. Accordingly, several crimping means can beoperated in a space that can be easily supervised by one operator who isable to rapidly produce several crimped connections. For this reason,these crimping means can also be arranged in series in production lineswithin a very small space.

Furthermore, the crimping means can use an entirely pneumatic drive,which has substantial advantages over drives containing electricalcomponents, particularly with respect to susceptibility to breakdown.

The crimping tools or ram members of the crimping means can be replacedby loosening a single screw. Since it is possible to keep differenttools available for different crimping processes, conversion fromcrimping of one type of terminal to crimping of another type is effectedrapidly and without any adjustments. Even a small production run ofcrimped connections can be made with the crimping means of the inventionsince such means is economical.

It is the primary object of the invention to improve the production ofcrimped connections between a wire and a terminal part.

It is another object of the invention to automatically eject a crimpedconnection from the apparatus which does the crimping.

It is another object of the invention to remove insulation from the wirebefore a crimped connection is made.

It is a further object of the invention to feed the terminal part to becrimped.

It is yet another object of the invention to coordinate and sequence allof the above discussed objectives.

These and other objects are considered in the following detaileddescription.

DETAILED DESCRIPTION OF THE DRAWINGS Referring to the drawings, twohorizontal cylinder holders 3 are fastened by screws 4 to verticalsupport plate 1. Holders 3 carry press operating cylinder 5 whose pistonrod 7 is movable between and parallel to cylinder holders 3. An uppertoggle lever 11 and a lower toggle lever 12 are swingably supported viatwo toggle lever bolts 9 on the free widened end 8 of piston rod 7. Theother end of upper toggle lever 11 is pivotally connected via togglelever bolt 13 with press force regulating device 17. Device 17 is firmlyconnected with two guide rods 21, which extend downwardlyin FIGS. 1 and2 parallel to plate 1. Crimping cylinder 5 with cylinder holders 3 isdisplaced laterally with respect to guide rods 21 such that togglelevers 11 and 12 move apart and move along the pair of guide rods 21.Guide rods 21 are guided for sliding in guide bushings 3 by guides 23.Guides 23 are fastened by screws 27 to front plate 1.

Lower toggle lever 12 is pivotally connected via toggle joint bolt 15with upper tool holder 29, which is guided via guide sleeves forvertical displacement on guide rods 21. Upper tool holder 29 isconnected to lower toggle lever 12. Holder 29 supports an upper tool 31,which is held by fastening screw 37 in a correspondingly shaped recessin tool holder 29. On its lower side, upper tool 31 carries upper ram33, which can be adjusted in length with respect to tool 31, forinstance by set screws (not shown).

The lower ends of guide rods 21 are rigidly connected to lower toolholder 41, which supports terminal part end price guide 48. On lowertool holder 41 and aligned with and laterally spaced from upper tool 31,lower tool 42 is fastened by means of holding screw 44 with adjustableram 46.

Between upper tool holder 29, which slides on guide rods 21, and lowertool holder 41, which is rigidly connected to guide rods 21, piston rod60 is fastened with holding piece 62 to the guide rod closest to thetools, and rod 60 is oriented parallel to cylinder holders 3. Rod 60 ismoved in and out of insulation stripping cylinder 50 by thathydraulically operated cylinder. Cylinder 50 carries externalreadjustment nut 54 thereon, carries internal piston sealing packages 58and carries cylinder body 56 on which readjustment nut 54 is screwed.

Connecting piece 70 is firmly connected to cylinder body 56 and extendsperpendicularly to the axis of insulation stripping cylinder 50 andguide rods 21. Connecting piece 70 supports severing cylinder 64. Pistonrod 68 is moved in and out of cylinder 64 by the hydraulically operatedcylinder. Piston 68 extends transversely across and over insulationstripping cylinder 50 and rod 68 protrudes laterally at the height ofthe upper 31 or lower 42 tool in a bore hole in an outer, movable knifeholder 72.

Movable knife holder 72 -is clamped by clamping screw 78 firmly over theend of piston rod 68. Connecting piece 70 supports fixed knife holder86, which is spaced in the direction of piston rod 68 from holder 72 andis aligned with and parallel to movable knife holder 72. The two knifeholders 72, 86 are accordingly perpendicular to both the axis ofsevering cylinder 64 and to guide rods 21. Each holder carries arespective knife 74 at its free end, which knives are fastened by knifeclamping screws 76 to the respective knife holders 72,

At its free end, each knife 74 has a dovetail shaped cutout 77. The cutouts define a diamond shaped opening. Knife holders 72, 86 are of suchlength that knives 74 are displaceable with respect to each other in themanner of scissor blades. Oriented to be between knife holders 72 and 86and spaced from cutout 77, stop 80 for infed wire is arranged onconnecting piece 70. Stop 80 actuates a pneumatic switch (not shown)which stops feeding of the wire.

In order to guide movable knife holder 72, guide bar 106 (FIG. 4) isfastened to knife holder 72, is oriented parallel to piston rod 68 andis guided for sliding movement in a corresponding bore hole inconnecting piece 70.

Driver 82 is fastened to connecting piece 70 and extends, as shown inFIG. 3, through slot 104 in end piece feeder 48. The chamber of endpiece feeder 48 includes end piece guide tunnel 91 with inlet opening 904 and outlet opening 92 in the end walls of end piece feeder 48. Endpiece guide tunnel 91 is limited on top by two guide rails 94, whichextend inwardly from the side walls of feeder 48. The chamber is dividedby guide rails 94 into end piece guide tunnel 91 below and into drivertunnel 95 above.

Plate shaped end piece pusher 96 is arranged for horizontal displacementon guide rails 94. Pusher 96 carries perpendicularly upwardly extendingfront stop 98 and spaced away rear stop 100. Driver tongue 102 is sofastened to the bottom side of end piece pusher 96 that it extendsbetween guide rails 94 into end piece guide tunnel 91. Tongue 102 is soinclined with respect to the plane of feed that upon movement of endpiece pusher 96 in the direction toward entrance opening 90, it movesresiliently over terminal part end pieces 101 of a cable end piecechain, which is inserted into end piece guide tunnel 91. But, uponmovement of end piece pusher 96 in the direction toward outlet opening92, it engages on an end piece 101 and transmits the movement of endpiece pusher 96 to the end piece chain. End piece pusher 96 is driven bydriver 82, which comes into contact with one of the two stops 98 or 100,depending on the direction of movement of pusher 96.

Two drivers 39 extend through slots in front plate 1 and are firmlyfastened on upper tool holder 29, previously described as beingsupported for sliding on the guide rods 21. One driver pin 39 is firmlyconnected with displaceable stop driver 126. The other driver pin 39 isconnected with displaceable stop driver 132, which is movable verticallyin guide groove 134.

Stop 130, fastened to stop driver 132, acts on latch 136. The latch ispivotally fastened to support plate 1 by means of pivot pin 138. Pin 138is at the end of the latch which is opposite the end that faces cablefeed slot 84. The end of the latch that faces that edge of plate 1 thatis provided with feed slot 84 has an angular contact surface 137, withwhich the upper end of ejector 108 is operatively connected and that endpivots vertically around pin 138.

Ejector arm 108 is pivotable horizontally around pivot pin 110 insupport plate 1. The ejector 108 is dimensioned such that when itpivots, its lower end, which is provided with cable grasping opening155, moves horizontally lengthwise along feed slot 84. The upper leverarm of ejector 108 is operatively connected with latch 136. It also hason its side a vertical groove 133 into which tooth 139 of drop pawl 112can engage.

Drop pawl 112 is elastically connected with ejector 108 via tensionspring 120, which is fastened in bore holes 114 in drop pawl 112 and inejector 108. Tension spring is fastened to ejector 108 below pivot pin110. The spring tends to pull the lower part of ejector 108 toward theinside of feed slot 84. Drop pawl 112 is pivotally movable horizontallyin FIG. 6. Pawl 112 is fastened by pivot pin 116 to drop pawl lever 121.

Drop pawl lever 121 is connected, approximately at its center, withsupport plate 1 by means of pivot pin 122 and lever 121 pivotsvertically in FIG. 6 around pin 122. That end of lever 121, which is notconnected with drop pawl '112, is inhibited from moving and thereafterpermitted to move by stop 124, which is fastened to stop driver 126.

Stop driver 126 travels in guide groove 128 in a direction parallel tostop driver 132. Driver 126 is connected by one driver pin 39 with uppertool holder 29.

The lever arm of drop pawl lever 121, which is connected with drop pawl112, is connected by tension spring 152 with wire retention means holder142, which is rotatable about pivot pin 144 in plate 1. The lever arm ofholder 142, which is connected with tension spring 152, has retainingsurface 154, which swings transversely to the direction of extension ofand in and out of the region of feed opening 84 upon the pivoting ofholder 142. Spring 152 draws guide surface 154 of holder 142 upwardly.Another corner of holder 142 has a hole 146 in which tension spring 148is hooked. The other end of that spring (not shown) is an chored firmlyto plate 1.

Tension springs 148 and 152 bias retention means holder 142 upwardlyinto feed slot 84. A corner of holder 142 that lies approximately aboveits pivot 144 is generally rounded in shape and is seated rotatably in aball mount of piston rod 149 that extends from and is hydraulicallymovable in and out of hydraulically operated retainer cylinder 140.Holder 142 is pivoted by the horizontal movement of piston rod 149.

I The manner of operation of the crimping means is now described.

The end of an insulated wire or cable is introduced through feed slot84. At this moment, piston rod 68 projecting froom severing cylinder 64is fully extended, so that knife holders 72 and 86 are at their maximumdistance apart, and the opening formed by the two dovetailed cuttingsurfaces 77 of knives 74 is open, in FIGS. 2 and 5. Piston 52 projectingfrom insulation stripping cylinder is entirely retracted. Therefore,knives 74, connected with cylinder body 56 by connecting piece are asnear as possible to plate 1, i.e. their position of FIG. 1. Piston rod 7projecting from and operated by crimping cylinder 5 is entirelyretracted. The cable wire is introduced between knives 74 and knifeholders 72 and 86 until the cable presses switch operating stop inward.This actuates severing cylinder 64 to retract its piston and piston rod68 inwardly. Knives 74 move past each other closing the dovetailedopening 77 in scissor like fashion untilthe insulation on the wire iscut.

Simultaneously with the actuation of severing cylinder 64, retainingcylinder 140 is actuated, and its piston rod 149 is retracted inwardly.Thereupon, retention means holder 142 swings counterclockwise upwardlyinto the position shown in FIG. 6. This clamps the wire fast betweenretaining surface 154 of holder 142 pressing from below and the walldefining cable grasping opening 155 of ejector 108 from above. The layerof insulation on the cable is severed by knives 74 sliding over eachother. By means of a pneumatic switch (not shown), insulation strippingcylinder 50 is actuated after the completion of the severing movement ofknives 74. Piston rod 60 extending from insulation stripping cylinder 50is firmly connected with one guide rod 21.

Cylinder body 56 with adjusting nut 54, connecting piece 70, driver 82,knife holders 72 and 86 and their knives 74 all move away from supportplate 1. As a resalt, the cut layer of insulation on the wire is pulledoff by knives 74. Driver 82, upon its path to the right in FIG. 3relative to fixed end piece feeder 48, contacts rear stop and moves endpiece pusher 96against introduction opening 90. Driver tongue 102 isalso pulled in the same direction over an end piece. The positions ofknife holders 72, 86, severing cylinder 64 and 6 adjusting nut 52 afterthis movement are shown in broken lines in FIG. 1.

When the insulation stripping movement has reached this rear position,press cylinder 5 is actuated by means of another pneumatic switch (notshown). Piston rod 7 moves outward, to the left in FIG. 1. As a result,via upper toggle lever 11, press force regulating device 17 is raised,which raises guide rods 21 to lift lower tool holder 41. At the sametime, upper tool holder 29 is moved downwardly by means of lower togglelever 12, relative to support plate 1 and to upwardly moving guide rods21. By the stripping movement, to the right in FIG. 1, of knives 74, theknives and their knife holders 72 and 86 have been moved out of theregion of the rams, so that tools 31, 42 with respective rams 33, 46 canmove without obstruction toward the cable plane. A cable terminal partend piece 101 lies on lower ram 46 and is raised with it to the crimpplane or the cable plane. End piece 101 is finally crimped onto thecable (not shown) by the interengagement of upper ram 33 and lower ram46 in the plane in which the cable has been introduced. Thereupon thetwo rams 33, 46 are loosened and separated and the crimped connectionremains.

FIG. 6 shows the system of levers for ejector 108 and retention meansholder 142 at the time of crimping. When holder 29 for the upper toolmoves upwardly, the two stops 124 and 130, together with stop drivers126 and 132, are pushed upwardly by driver pins 39 which are fastened toupper tool holder 29. The upward movement of stop 130 swings up latch136, and the latch disengages from ejector 108, permitting the ejectorto swing counterclockwise in FIG. 6 toward the open end of feed slot 84.At the same time, drop pawl lever 121 is released for clockwise rotationin FIG. 6 by upward movement of stop 124. The pulling force produced bythe pull of tension spring 152 on lever 121 pulls the lever clockwiseand this clockwise motion is transmitted by drop pawl 112 to contactsurface 133 between drop pawl 112 and ejector 108. Since this contactsurface is eccentric with respect to pivot pin 110 of ejector 108, thedownward motion of pawl 112 causes counterclockwise rotation of ejector108.

Simultaneously with the separating of rams 33, 46, retainer cylinderpushes piston 149 outwardly. As a result, retention means holder 142 andthus retainer surface 154 are pivoted out of feed slot 84. The crimpedconnection which now lies loosely in cable grasping opening 155 isreleased. This pivoting of holder 142 tensions spring 152 further. Whenejector 108 is pivoting outwardly of slot 84, the crimped connection isthus freed and is pushed out of feed slot 84. When ejector 108 haspivoted through a predetermined angle, the crimped connection drops outof cable grasping opening 155 and feed opening 84. Drop pawl 112disengages by means of tooth 139 from out of tooth gap 133, whereby nomoment of rotation is any longer exerted by drop pawl 112 on ejector108. The ejector is pulled back into its original position by the pullof tension spring 120, and in this position, drop pawl 112 can againengage it.

As shown in FIG. 2, the pressing force can be adjusted by means ofregulating screw 19. This is effected in the following manner: Byturning of regulating screw 19, gear 160, which is arranged coaxially toregulating screw 19, is turned. Gear engages gears 162 which have wormgear interiors and which are fixed axially with respect to guide rods 21in housing 18. The worm gear interiors of gears 162 engage worms 164 onguide rods 21. By the turning of gear wheels 162, guide rods 21 areadjusted up and down to a greater or lesser extent. This movement istransmitted to lower tool holder 41. By this adjustment of the effectiveguide rod length, the distance between rams 33, 46, and thus thecrimping force, is adjusted.

Although the present invention has been described in connection with apreferred embodiment thereof, many variations and modifications will nowbecome apparent to those skilled in the art.
